I am currently using Windows 7 64bit Home Premium Service Pack 1. I bought this router and it worked fine for about a week and then it started acting up and dropping my wired connection and taking ten minutes to load a page and now when I get on the router's page to look at the settings and forward a few ports, it isn't loading all the way.
It looks like this when logging in.

When I click on the Tools tab and other tabs as well information isn't showing up and they look like this

And when clicking through the tabs and menus I get 9 times out of 10, a page that says "Unable to Connect".
Does someone know how to fix this? If you need more information just ask please.
